To all ce hom z5 41mg/ Vconcer/1i- Be it know-n that I, CHARLES A. KUNZ, a citizen yof `the United States, residing at Dubuque, in the lcounty of Dubuque and vState ot Iowa, ,have invented `certain new and Vuseful Improvements in Dust Collectors; Aand I do hereby `declare itlie following to be a lfull, clear, Vand exact description oic the invention, such as will enable-others skilled in the art lto which `it -appertai-ns to make and use thesame. l

This invention relates (to idgust Vseparators and collectors, and more particularly to an.

improved `forni of ydust separator and collector which will gpositivel-y separate the dust from `.the dust laden air which is `fed `into the apparatus and `collect the same `in `the bottom of the inac'hine, while the 4cleansed or .puriiied air is discharged Ithrough one or more screened exits or ven- :tilators :at the top of :the apparatus.

. :tional `view of niy vimproved dust separator :and collector.;

.-Fig. 2 is :a transverse lsectional view 'through fthe same; and

:Fig is a gplan view partly 'broken away in section.

Like characters oli lreference ,are used ,throughout `the ttollowing specification and the accompanying drawings to designate corresponding parts.

My improved duetseparator and collector comprises la `substantially air-tight housing l, which inay be of any desired shape, and

vis provided with asuitablecollecting chute 2 Vat lthe bottoni whereof, whiehiu turn `may be provided with a controlli-ng` Avalve o.

A yconveyor tube .4 is positioned to 4extend into and :above the housingl, and is i lila-red outwardly `fat ,its .upper end to forni Vthe head or top portion 5. A dust andair receiving tube 6 ris yprovided with a ,flared inner end 7 andconnects `with the ,saidcoir veyor ltube 4. The outer end of the tube G is connected 4to a suitable pair collecting fan (not shown), which is iadaptedfto .draw the dust laden `air '-into the -receivingftube 6 and force .the .saine through .the :conveyor tube .both in an upward Yand downward direction.

vI preferably provide three ydownwardrly extending discharge tubes 1S, the-same `being connected in spaced yrelation about ithe1 flared yhead 5 andare in direct communication therewith. .housing `l and `terminate adjacentrthe bottoni thereof, andere directed outwardly .at a slight angle, as clearly illustrated in 'the drawings.

The upper end lot' the conveyor tube 4 is closed by means of thefspaced layer-s of cloth -9 and `netting [10, ywhich are :suitably secured to the vinterposed spaced slats 11, and serve to 'sieve 'ithe dust from -the ,dust Pladen air so ythat the same will fall lthrougji the fdischa-rge tubes 8 into the bottom 2 o-thehousing'l, `while the I:pure iair -will pass .through Ilche cloth -9 andnetting `-10 and vout ithrou'gh the ventilator 1Q. vided with a ,plurality of :bearing lwheels '13, which are adapted 'to run-on fthe vcollar `lll positioned about lthe .upper end Vof the .top Iportion 5, and normally moves fwiththe direction of fthe wind. It is preferable that f the discharge Vtube 8 Vbe approximately one third the diameter of the :conveyor tube 4; ttor best results; to `be 1had when :the-apparatus is .in operation.

A vertically adjustable air distributing" tube 15 of considerablylarger diameterfthan the conveyor tube .Il is supportedin :spaced `relation about lthe tube 4; ib-,y yiijieans of the screws lr6, which :extend through thetop :of -the housing land through the nuts 17. The 100 ylower end not the tube l5 Lis provided with iafflange or skirt .18, about the ,edge of which are ldisposed a plurality vof :lengths of ,cliain 19, which are adapted `:to collect .the dust,

until fthe saine drcpsofin y.chunks'or :solid "105 mieees and falls into Y.the ,collectingehute 2.

@ne portion of the housing l is :formed into an air box or compartment l2() and is provided with the front andbottoinfslatted drames 2l and 22,-whichiagrefhingedftegether 110 The tubes 8 .extend intO th-f the head portion l 5 iot The ventilator 112 is pro mounted in the brackets 33. The eccentrics 34 on the shaft 32 are connected with the eccentric rods so that the frames 21 and j 22 will be vibrated.

The frames 21 and 22 are covered on their inner surfaces with a suitable netting or mesh 35, and are covered on their outer sides by the cloth, rubber, or canvas 36, which extends beyond the sides and en ds of the said frames, and is secured to the inner walls of the housing 1 so that the frames and covering constitute a tightly closed air chamber.

An air discharge tube 37 extends through the top of the housing 1 and connects with the Yair chamber 20. An angle track collar 38 is positioned about the tube 37 on which run wheels 39 pivoted on the lower end of the ventilator elbow 40. Suitable packing may be used in the joints between the elbows 12 and 40, if desired. The elbow t() will loe adapted to turn with the direction of the wind.

` From the foregoing description it will be apparent that the modus operandi is as follows: The dust laden air from a 'factory or building will be drawn by a motor driven fan into the inlet lube 6whence part of the same will tra-vel upwardly, and part downwardly in the .inlet tubel t. The air which travels upwardly impinges against the cloth 9, and the cleansed air passes thro-ugh the ventilator 12, while the dust and a small portion of the air passes down through the discharge tubes Si, whereupon the dust falls into and collects in the chute 2. The air which moves downwardly passes through the distributing tube 15, and most of the dust will collect on the chains 19, where it will finally drop into the chute 2.

The motor 27 will be continually vibrating the frames 21 and 22, and the dust striking the cloth or canvas covering the said frames will be thrown or deposited in the chute 2, while the air which passes through the cloth 3G and netting 35 will be thoroughly cleansed and will pass out through the elbow ventilator 40.

Thus it will be understood that the impure, dust laden air from factories or the like may be continually cleansed, and the pure air discharged back into the surroundin@ atmosphere.

lIany minor changes in detail of constructioninay be resorted to without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A dust separator and collector comprising a housing, a vertical conveyor tube extending therein, an air inlet tube communicating with said conveyor tube substantially above the inner end thereof at an angle thereto, and a screened ventilator at the outer end of said conveyor tube.

2. A dust separator and collector comprising a housing, a vertical conveyor tube extending therein, an air inlet tube attached to and communicating with said conveyor tube at an angle thereto and above the inner end thereof, a screened ventilator at the outer end of said conveyor tube, and a plurality of discharge tubes adjacent said screened ventilator terminating adjacent the bottom of said housing.

8. A dust separator and collector comprising a housing, a conveyor tube extending there-in, an air inlet tube attached to said yconveyor tube, a flared head formed on the upper end of said conveyor tube, a screened ventilator at the outer end thereof, a discharge tube extending from said flared head within said housing, and a vertically adjustable distributing tube positioned about said conveyor tube.

4. A dust separator and collector comprising a housing, a conveyor tube extending therein, an air inlet tube attached to said conveyor tube, a head formed on the upper end of said conveyor tube, a screen ventilator at the outer end thereof, a discharge tube extending from said'flared head within said housing, a vertically adjustable flanged distributing tube positioned about said conveyor tube, and a plurality of dust collecting chains depending from Said flange on said distributing tube.

5. dust separa-tor and collector comprisingk a housing, a conveyor tube extending therein, an air inlet tube attached to said conveyor tube, a head formed on the upper end of. said conveyor tube, a screen ventilator at the outer end thereof, a discharge tube extending from said head within said housing, a vertically adjustable flanged distributing tube spaced about said conveyor tube, dust collecting means at thev lower end thereof, and a dust collecting chute at t-he bottom of said housing.

6. A dust separator and collector comprising a housing, a dust collecting chute at the bottom thereof, means for admitting dust laden air to said housing, means for distributing said air within said housing, a screened discharge ventilator in communication with said housing, a screened air kcompartment formed within said housing and hingedly connected thereto, means for vibrating the llO walls oit said compartment, and a second discharge ventilator extending from said air compartment through said housing.

7. A dust Iseparator and collector comprising a housing, means for admitting dust laden an' therein, fixed means Within said housing for separating the dust from said nir, a screened discharge ventilator in communicution with said fixed dust Separating' means, a vibrating dust separating means Within said housing, and a Second discharge ventilator in communication therewith.

In testimony whereof I affix my signa* ture.
